Screen printing features
1. It is not limited by the size and shape of the substrate. Generally, the screen printing mesh can only be carried out on a flat surface, and the silk screen printing can not only print on a flat surface, but also print on a special shape of the molded object and the uneven surface, and can also print various kinds. Very large advertising paintings, curtains and curtains. For example, at present, the printing area of general offset printing, embossing and the like can print a maximum size of a full sheet, which exceeds the full sheet size and is limited by mechanical equipment. Screen printing can be used for large-area printing, with a maximum format of up to 3m x 4m or even larger. It can also be printed on ultra-small, ultra-high-precision items, and can also be printed on curved or spherical surfaces. This printing method has great flexibility and wide applicability. All shapes and shapes can be printed with silk screen. Screen printing is also possible for those special surfaces.
2, the layout is soft and small
Screen printing is soft and flexible, and has a small printing pressure. Therefore, it can be printed on soft substrates such as paper and textiles, and can be printed on various types of glass and ceramic ware that are easily damaged by pressure.
3, the ink layer is thick and strong
The thickness of the ink on the relief and slab prints is only a few microns, the gravure printing is only 12-15 microns, and the thickness of the screen printing ink can reach 30~100 microns. Therefore, the hiding power of the ink is particularly strong, and it can be used in all black paper. Printed on pure white for printing. In addition, printing such as circuit boards and oil paintings can be performed using the characteristics of ink thickness. Braille lettering printed with foaming ink, the thickness of the ink layer after foaming can reach 300 microns. The screen printing ink layer is thick, and the printed graphic has a strong three-dimensional effect, which is unmatched by other printing methods. If the printing method of one moving is to cover the underlying color with white, it is necessary to copy the same part 3~4 times, and the screen printing can be completed once. Since the thickness of the ink layer is good and the three-dimensional feeling is good, the application is very wide. Of course, the thickness of the ink layer can also be controlled.
